Abstract
Bu çalışmada kulaklı orman baykuşunun (Asio otus) pelet içerikleri analiz edilmiştir. Bu çalışmanın temel amacı, kulaklı orman baykuşunun yaz mevsiminde bir dağ bozkırındaki diyet kompozisyonunu araştırmaktır. Kulaklı orman baykuşuna ait 130 pelet içeriği çalışmada kullanılmıştır. Pelet içeriğinden 9 farklı taksona ait 147 av (pelet başına 1.13 av) olduğu belirlendi. Küçük memeliler türün diyetinin en önemli kısmını oluşturmaktadır. Yalnızca iki tane kuş kalıntısına peletlerde rastlanmıştır. Microtus sp., türün diyetinde önemli bir av olarak tespit edildi (F =% 81.63, B =% 78.21). Microtus sp. kulaklı orman baykuşunun favori avı olduğu için bu durum diyet içeriğindeki av çeşitliliği ile negatif korelasyona sebep olmaktadır. Bu nedenle FNB ve Shannon-Wiener indeksi düşük değerdedir.

Abstract
In this study, pellet compositions of Long-eared Owl (Asio otus) were analysed. The primary aim of this study was to investigate the diet composition of Long-eared Owl in high altitude steppe in summer. Compositions of 130 pellets of Long-eared Owl were used in the study. 147 preys (1.13 preys per pellet) which belong to 9 different taxa were found in pellet composition. A significant part of the diet in study area consisted of small mammals. Only two remains of birds were recorded from pellets. Microtus sp. was found important prey in the diet of Long-eared Owl (F = 81.63 %, B = 78.21%). Since Microtus sp. is the favourite prey of Long-eared Owl, this situation causes a negative correlation with the prey variety in diet composition. For this reason, FNB and Shannon-Wiener indices had low levels, Shannon-Wiener (H’) value was found to be low for Long-eared Owl.
